Unreal Replication

Purpose

Implement and review Unreal replication with explicit ownership, relevancy, authority, and failure behavior.

Use When

• the project has replicated gameplay
• bandwidth or authority bugs are appearing
• client/server ownership is unclear

Inputs

• authority model
• class ownership map
• prediction requirements
• network constraints

Process

1. define what replicates and why
2. assign ownership across GameState, PlayerState, Controllers, Pawns, and Actors
3. choose relevancy and update strategy intentionally
4. test disconnect, reconnect, and edge latency cases
5. profile bandwidth and churn in realistic sessions

Outputs

• replication model
• ownership matrix
• failure handling rules
• profiling targets

Quality Bar

• respects Unreal framework ownership, packaging, and content pipeline realities
• keeps C++, Blueprints, plugins, and content boundaries intentional
• makes replication, map setup, and packaging risk explicit

Common Failure Modes

• Blueprint graph sprawl hiding ownership
• using Tick where event-driven logic is clearer
• packaging or plugin state changing without documentation

Notes

• Keep this skill aligned with the relevant rules layer and current project documentation.
• If engine-specific constraints materially change the workflow, hand off to the matching engine skill or engine-specific reviewer.
